Hot water questions from Mortdale
Clear answers to common hot water questions from Sydney homeowners.
How much does it cost to run a hot water system?
Running cost depends on hot water use, energy tariff, system efficiency, climate and losses from storage and pipework. The energy label or manufacturer data provides a starting point, but household shower duration and flow rate often have the greatest practical impact.
Can I run a heat pump hot water system from my solar panels?
Yes. Setting the heat pump to run during daylight hours allows it to use rooftop solar generation. Because it consumes relatively little electricity while heating, the combination can produce very low hot water running costs.
What size hot water system do I need?
Sizing depends on household size, shower flow rates, peak usage, available energy supply and the systemβs recovery rate. A small tank with fast recovery can suit some homes, while larger families or simultaneous showers may need greater storage or continuous-flow capacity.
What is an expansion control valve (ECV), and does my hot water system need one?
An ECV relieves cold-water-side expansion as the stored water heats. Whether one is required depends on local water authority conditions, the valve arrangement and manufacturer instructions.
Why is my solar hot water booster running all the time?
The timer or controller may be set incorrectly, a sensor or circulation fault may be preventing solar gain, or household demand may exceed the available solar heat. Continuous boosting defeats much of the systemβs energy-saving benefit.
